I have just read this thread from start to finish and what a car it is! That must really shift! It is great to see that someone has shown some Orions love . I have to say that this car is superb and I adore the looks of the red one!
I may need to have a chat to you about the Quaife LSD. I need to swap the clutch in my RST for a hybrid combo (4 paddle centre and stock cover) and replace my open diff for an ATB, which I assume you are running.
TBH I see wheelspin in second gear in my RST and that is with 230BHP! I am trying to resist going further but I know a Quaife is most likely to be in the pipeline and possibly even standalone management if I get the £££ and keep it long enough. The MPG is simply terrible ATM even if it is on KE-Jetronic.
